Question

Assertion [A]: A stone has a definite shape.
Reason [R]: The particles of a stone are held together by strong intermolecular forces of attraction.

Which among the following options are correct?

• A. Both [A] and [R] are incorrect
• B. [A] is correct, but [R] is incorrect
• C. Both [A] and [R] are correct
• D. [A] is incorrect, but [R] is correct

Answer 1

The correct option is C Both [A] and [R] are correct

Solids have a strong intermolecular force of attraction between their particles. Due to this force, they have less interparticle space. Hence, they have a definite shape and volume.

A stone is a solid. It possesses all the mentioned properties. Thus, it has a definite shape due to the strong intermolecular force of attraction.
